摘要
The sound velocity, V, of 10 MHz longitudinal waves propagating along [100] was measured near the Néel point, TN, of MnF2. The result is expressed as V ≈ (T-TN)-v with v=0.132 for T > TN. This value of v is the same as that in the power-law expression for the variation of the attenuation coefficient. © 1974.
